A red blur was spotted moving through the streets of Perth's southern suburbs yesterday, prompting more than one passing motorist to do a double take as they took in the familiar furrowed brow of the man crouched low over his bike.

Those who slowed long enough to get a good look at the cyclist's face would have seen the focused gaze of last year's Tour de France winner.

News that Cadel Evans was coming to Perth broke last month but details of his arrival and movements were a well-kept secret.

Evans hit the streets around Fremantle, Mt Pleasant, Shelley and Victoria Park yesterday at the behest of accounting giant Ernst &Young, whose corporate relationship with the pacesetter predates the Tour win that made him a household name.

At his heels was a 90-strong peloton, comprising company partners, clients and their family members.

The 80km ride began and ended at North Fremantle's Salt on the Beach restaurant, where Evans and the group stayed on for lunch.
